IMPROVEMENT IN CASKS AND BARRELS.

Specification forming part of Letters Patent No. 58,82l, dated October16, i866.

experiment.

The nature of my invention or improvements consists in rabbetiug outtheedges ofthe staves, and heading and nlling the rabbets with a spline orstrip, glued, cemented, or otherwise, to cover the joints between thestaves or pieces ot' the heading; and in driving some pins, glued,cemented, or otherwise, through the splines or strips into the staves,to aid in fastening them; also, in some pins between the staves in thechine of the cask, glued, cemented, or otherwise; also, in cutting therabbets under or inclined, to receive dovetailing strips or splines.

In the accompanying drawings, Figure l is an elevation ot' the side ofthe barrel with my improvements. Fig. 2 is an elevation of one end.

In these drawings, A A are the staves of the barrel, made of wood in theusual manner, either by hand or by machinery, and rabbets are cut intheedges at the outside corners, which rabbets are cut under, as shown inthe drawings, so that when the staves are put together these rabbetsform dovetailin g grooves, which are filled by the strips or splines BB, to cover the joints between the staves. These splines should be madeso wide that when the hoops C C of the barrel are driven and the stavespressed together they will press the splines Very tight, so as toprevent the joint from leaking. Babbets are also cut in the pieces D Dof the heading in the same way7 and splines put in to make the joints inthe heads tight. These splines may also be glued or cemented, and thesesplines may be further fastened by pins or nails driven through theminto the staves in an inclined direction, as shown in the drawings; andif pins made of wood are used, they may be glued or cemented 1n.

After the barrel is put together, and before the chine-hoops are drivenquite home, I bore holes between the staves or in the joints between thestaves, close to the edge of the head, and drive pins E E in the holes,with glue, cement, or otherwise, so that the pins spline the jointsbetween the staves, at the ends, from the edge ot' the head to thesplines B B between the staves; and after driving the pins between thestaves the chine-hoops are driven home to make the whole tight.

My improved barrels are designed for kerosehe-oils and burning-Huids ofdifferent kinds that require a very tight barrel.

What I claim as my invention or improvements in casks or barrels is- 1.Rabbeti-ng out the edges of the staves, and heading and filling therabbets with a spline or strip (glued, cemented, or otherwise) coveringthe joints between the staves or pieces of heading.

2. In combination with the splines, the pins, glued, cemented, orotherwise, as aids in fastenin g the splines.

3. The pins between the staves in the chine of the Cask, glued,cemented, or otherwise.

4. Cutting the rabbets under and making the splines or stripsdovetailing, substantially as described.
